IMPROVEMENT IN HQES.

'-The Schedule referred to ,in these Letters Patent and making part of the same.

To all whom. tt mm] concern Beit known that we, JAMES FAmLnY 'and ALFRED FAIRLEY, of Birmingham, England, have invented a new and useful Improvement Yin Plantation and other Hoes and other Farm Implements; and we do hereby declare that the following is a full, clear, and exact description. thereof', which will enable. those skilled in the art to make and use the saine, reference being had to the accompanying drawing forming part of this specification.

This invention relates to a new and improved method 'of constructing the eyes or sockets of hoes, rakes, and other agricultural implements, and attaching the same thereto, whereby' ahoc, rake, orother implement may be at any time easily detached from the socket and another substituted iu the place thereof. 4

It consists in the manner of constructing the socket and in the manner of shaping and punching the blade of the implement,so that any'blade' so shaped and punched lwill tit, and may be at any time quickly secured to and detached from said socket.

In the accompanying drawing- Figure l is a front view of our invention in 'one form, with a rake att-ached.

v Figure 2 is a central vertical section of the saine,

taken in the line y y, tig. l;

. Figure 3 is a front viewvof the same form, with a hoe attached. Figure 4 isa central vertical section of the same,l

taken in the line w w, iig. 3.

Figure 5 i? a front view of the same, with a smaller hoe attache( Figure 6 is afront view ofthe blade of a hoe, showing the form and manner of punching the same.

Stimilar letters of reference indicate corresponding par s. A is the blade ofthe implement, and

B is the socket, made of wrought, cast, or other suitable iron.

The eye of the socket B is made ofthe same general form as the eyes of the sockets of hoesaud other like agricultural implements, and receives the handle by means of which the hoe is operated, said eye having on' the under side of the same, extending downward and being a part thereof or rigidly secured thereto, a bit to which the blade of the implement is secured, as hereinafter more fully set forth.

The bit of the socket may be made of any desired length, and having the requisite angle with relation to the handle and blade A.'

The bit of the socket B is enlarged i n the lower end of the same to present a greater bearing surface to the backof the blade ofthe implement, and also to receive, through a hole bored in the same, the screw-bolt a2, countersunk in its back, said countersluk being oi' sucient depth to contain the head of the screw-bolt a2, and of snicent diameter -to receive vafwrench, by means' of which the bolt cis turned.

The front of the bit is depressed so as to form a plain vface', against which the back of the blade of the implement is placed, and so as to leave ashoulder projecting in front. v

Into said shoulder, and upward toward theceye of the socket, is a slot or mortise, e', as .shown in the drawing, 2. Ihis slot is in a line with the faceof the bit, and receives the back of the blade A.

Upon the face of the bit, below the shoulder above described, is formed a tongue or tenon, a, adapted to tit into the'slot a formed iu the blade A, shown in tig. 6.v

Upon the under side of the tenon ci is a slot or mortise, e, to receive the blade A. rlhis mortise'e is similar to and in a line with the slot c', so that theblade A, when placed upon the bit ot' the'socket, may be forced up into the slots c and c', as shown, said slots e and c being made slightly tapering on the front part, it necessary, to bind the blade A- more firmly against the bit.

lhe tenon as is ot sufficient depth to project through the slot ain the blade and beyond the same, so as to form another. shoulder on its upper part, which, with the shoulder above described, forms a recess to receivev the nut a. and. prevent its turning with the bolt a2.

The operation of attaching a blade A, whether a rake, or hoe, or other implement, to the socket is readily seen. The blade A is .placed upon the face of the bit of the socket and the slot a, of the same upon the tenon a. Ihe blade is thenforced upward into the slots c and e', 'and the bolt a2 passed through thehole in the bit above described, and through `the slot a of the blade, and turned into the nut al. The

lblade A is firmly held against the bit of the socket B,

and by unscrewing the bolt a? the blade A is easily removed, when another of different form may he substituted therefor.

' y In order that the blades of implements may be made for sockets above described, it is only necessary that the top of the same should be provided with a neck, f, (see fig. 6,) in the center ot' the top of the same to receive the bit of the socket B, and that aslot, a, be punched near the top ofthe. blade to receive the tenon a3. l v

Constructed as above described, they form sock-ets for the attachment ot' the blades of implements ern- `ployed in agriculture and for other purposes, the advantages ot' which are that the blades may at any time be removed from the sockets, or other blades-ot` other forms substituted therefor.

Having thus describedour invention, IVhat we claim as new,and desire to secure by Letters Patent, is

1. A blade for hoes or other implements, having a niek, f, and slot a, in Icombination with a tenen, a, and seals th'is second dey of November, in the year of and slots e e', on` a socket, B, substantially es shown our Lord one thousand eight hundred and sixty-seven. and described, for the purpose specified.
